【摘要】：目的揭示正常日本大耳白兔同步12导联心电图特征,为心血管疾病的实验研究提供心电图基本数据。方法雄性日本大耳白兔55只,20%乌拉坦腹腔麻醉,描记兔同步12导联心电图,并拍胸部X线正位片。结果心电图:1日本大耳白兔心电图波形与人类相似,均为窦性心律。心率较快,265.5±36.8次/min,未见心律失常发生;2仰卧位平均心电轴:19°~250°,波动范围较大;3 P波:形态钝圆或略尖,均符合窦性P波规律,在肢体Ⅱ、a VF导联及胸导联较为明显;4 P-R间期:(0.063±0.007)s;5 QRS波:QRS波时间为(0.040±0.005)s,主波在Ⅱ、Ⅲ、a VF导联多数向上,胸导联与人类相似,R/S比值逐渐递增;6 ST段:较短,均位于等电位线;7 T波:T波形态多圆顿,部分双峰,多数导联T波直立,部分倒置,平坦或双向。T波在肢体II、III、a VR、a VF及胸导联较为明显;8 QT间期:QT间期(0.142±0.015)s,QTc(0.306±0.034)s。胸部X线正位片:心影大多位于胸腔正中及右侧。结论获得了兔标准12导联心电图波形及其各波段的正常值范围,在心血管疾病的实验研究中具有一定的应用价值。
[Abstract]:Objective to reveal the characteristics of synchronous 12-lead electrocardiogram (ECG) in normal Japanese white rabbits and to provide basic ECG data for the experimental study of cardiovascular diseases. Methods 55 male Japanese white rabbits were anesthetized with 20% uratan intraperitoneally. The 12-lead electrocardiogram (ECG) of rabbits was recorded and chest radiographs were taken. Results the ECG waveforms of Japanese white rabbits were similar to those of human beings, all of them were sinus rhythm, and the heart rate was faster. No arrhythmia occurred at 265.5 卤36.8 rpm. (2) in supine position, the mean ECG axis was 20 掳to 250 掳, and the range of fluctuation was large; 3P wave: the shape was obtuse round or slightly pointed, all accord with the rule of sinus P wave, and were more obvious in the limb 鈪，
